You are unhappy with flies, ants, & cockroaches in your kitchen.
You are worried about houseflies’ contamination.
You are uncomfortable with an ugly and messy insect trap in your house.
You hate to clean dead flies.
You are anxious about children and pets touching dirty insect traps.
You want to throw the insects trap as a garbage bag.

There are significant flaws in existed insect traps such as:
- Insect is stuck on an open adhesive tape, dead body or part may fall down during cleaning up and disposal.
- Insect stuck inside a close adhesive box, it is difficult to check how many trapped death insects to decide when to clean ...

We use a robust, high-accuracy simulation model of the human head to optimize an American football helmet to reduce the likelihood of concussion and the long term development of Chronic Traumatic Encephalopathy (CTE). Sports related concussions have been in the spotlight ever since the discovery of CTE, which is a neuro-degenerative brain disease believed to be caused by repetitive concussive and sub-concussive impacts. There are hundreds of concussions reported in American football each year with evidence that nearly 90% of deceased football players had some form of CTE. Therefore, helmets that protect the brain from concussion and CTE are the need of the hour in the sports industry. Helmets on the market today are not equipped to protect the ...

Early detection of incipient failure and excessive wear in knee implants is essential to avoid revision surgery and hence lower medical costs. Self-powered embedded implants sensors could provide a new in vivo capability to reduce these clinical complications. A feasibility study is conducted on a self-powered embedded sensor. Passive body motions are converted to electricity through triboelectric transducers to operate low power load sensors.

The self-powered embedded sensor will be instrumented in TKR between the UHMWPE bearing and the Tibial tray, Figure1. It consists of a package designed with mechanical springs. Two identical triboelectric generators and power digitizing circuit embedded in knee implants inside the package. The generator consists of an upper electrode with micropatterns and the lower electrode ...

This solution is based on a strategy and an invention. Earth has its own system to balance its temperature. Human activity distrupts this balance. Earth reduces its temperature by ice poles as a natural cooling system. We should just help the poles to repair melted ice then reduce global warming. Setting cold blowers (invented system) by plane can produce or strengthen cold fronts at the poles to repair the cold ...

1) As already described in 2017 and 2018 entry a body sliding on an inclined plane can be supported by a thread or support perfectly parallel to the horizontal.The weight of a body that is unsupported even at the position of rest by this mechanism is maximum for a plane of inclination 45°as explained mathematically in preprint manuscript doi:10.5281/zenodo.439108 causing compression of spacetime below and expansion of space time above the supporting surface.Here technical modification is made to support the body by a perfectly horizontal thread or support on a plane of increased inclination by way of pressure by an elastic recoil force.

2) The modification has weight of body sliding on inclined plane IP1 and IP2 of lightweight ...

THE PROBLEM:
Inefficient capture, storage, and use of a vehicle’s kinetic energy (KE).

Specific issues include:
A. CAPTURING & STORING A VEHICLE'S KINETIC ENERGY:
Vehicles that experience frequent stop-and-start conditions have massive kinetic energy losses.
B. BATTERY TECHNOLOGY:
Batteries can supply current (discharge) at a far higher rate than they can absorb current (recharge).
C. TRACTION MOTOR USED AS A DYNAMO:
When a vehicle stops, its traction motor cannot function as a dynamo.
D. VEHICLE WEIGHT:
For a given velocity, light vehicles have less kinetic energy than heavy vehicles.

THE SOLUTION:
A. CAPTURE and STORE a VEHICLE'S KE as ANGULAR KE and ANGULAR MOMENTUM:
1. Vehicle's KE is captured and stored in sandwiched pairs of counter-rotating flywheels ...

Water is the most important resource, it connects every aspect of our lives. But due to increased population, deforestation, industrialization the water sources are being contaminated, depleting. Today, 1 in 9 people lack access to safe water.

Our proposed solution is a sustainable system which powers itself, monitors the water sources (gathering live data and analysis of the data from livers, lakes, ponds) and alerts officials if any of the parameters are above the standard threshold.

The bot will move through different locations collecting the data. The data is then analyzed to find water quality index. This can prevent contaminated water reaching the consumers and the data gathered can be utilized for further development.

Absolute, unlimited power generation.

Under the laws of physics, to produce electricity, a magnetic field must be inserted into the wire box.

Movement of the paddle in the vacuum does not stop because it does not have air resistance.

If we move the pendulum through the vacuum to the magnet and wrap the wrap around the pendulum, the pendulum does not stop, so we can replace the electric current that does not expire.

For some reason, the pendulum is slowly moving slowly, using a portion of the electric current that it generates. The remaining electric power remains purely.
Of course, millions of layers of them will have more electricity available. Most of all, it does not need water, steam, ...

Accexlron is a rapid prototyping micro-controller development board based on the high-performance RISC architecture based ATmega 2560. The board comes with a host of functionalities like: Built-in motor driver circuitry, Bluetooth and Wifi Plug--n-Play compliancy. Higher voltage and current thresholds, Greater Sketch Size and Higher Throughput of 16MIPS at 16Mhz clock speed. The board was primarily designed to eliminate redundant tasks like being vigil about the current and voltage supply, excess power supply that led to frying of your application. The board automates several redundant tasks, aids in hardware minimization while helping DIY-hackers, hardware startups and students alike in rapid ...

Acoustic Transducer Diaphragm - Boxless, Omnidirectional, Full-Range

US patent 7,860,265 Planot® acoustic transducer diaphragm. The most common electromechanical device in the world is the speaker. I have reinvented and vastly improved it. The first Planotary design under development; compact and VastFidelity™.

The Planot diaphragm pivots along its long axis; unlike previous Planots its bearings, as well as the magnet-homing-damping device, are housed “inside” of the diaphragm. The external support “mast” for the diaphragm is eliminated by the single, internal and stationary axle. The sound is improved, the cost is lowered and the size is reduced. This diaphragm has a surface area of 32 sq. in. A typical 6 inch speaker has an area of 21.21 sq. in.

“Omnidirectional is ...
